The new build of the popular MetaTrader 4 mobile platform for
iPhone/iPad is released with improved security. Now, you can set a PIN
code or use Touch ID to restrict access to the application. If your
iPhone or iPad falls into the hands of another person, your trading
account remains secure.

To activate the new function, enable Lock Screen in the Settings/About window and set a four-digit combination.

Update your application to try the new feature. The latest version of MetaTrader 4 is now available on the App Store!
